IMPROVEMENT IN GRAIN-BINDERS FOR HARVESTERS.

Specification forming part of dditional Improvement No. 140, dated April '3, 1556, to Letters Patent No. 14,036, dated January l, 1856.

To all whom it may concern:

Be it known that I, GEORGE W. N. YosT, of' Pittsburg, in the county ot' Allegheny and State of Pennsylvania, have invented certain additional improvements on the harvester patented by me January l, 1856; and I do hereby declare that the following is a t'nll, clear, and exact description ot' the principle or character which distinguishes it from all other things before known, and ot' the usual manner of making, modifying, and using the same, reference being had to the accompanying drawings, of which- Figure 1 represents a plan ol' the harvester; Fig. 2, a side elevation, showing the form ot' cams, Src.; Fig. 3, a perspective view otl the compressor a2 and slide-plate q, and showing the slat yr and manner ot adjustment; Fig. 4, a detached part of the plate-lever and spring, showing more clearly their connection with each other.

My invention consists in certain improvements in the harvester for which I obtained Letters Patent January 1, 1856, by which Iam enabled tooperate the reciprocatin gcompressor al with the required intervals at each point where the bundleis compressed the most, and to retain it at this'point a given length ot' time to enable the binder to complete the operation of tying and discharging the sheaves; also, for adjusting the compressors forward or backward on the platform for the purpose otnl ways having them to compress the bundle near the center, whether long or short grain is cnt; also, for preventing the cut grain from falling in the way of the binder while in the act ot' binding the compressed bundle, which l describe as follows:

0n the face ofthe driving-wheel a, I secure a continuous combination of cams, formed by two circular rims, b b'. These cams are formed by a continuous slot left between the rims b b', and ofthe shape shown in Fig. 2. On one end ot' the frame c, which supports the driving wheel, and pivoted thereto, is a small lever, d. The pivot d' serves as the fulcrum ot' this lever, one end ot which takes into the continuous slot e, and is operated upon by the peculiar form of this slot. The other end of this lever is secured between a small tlanged wheehf, keyed to the pinion-shaft y. This shaft has its bearings on tw'o arms, h h, projecting from the frame c, and is covered by caps h h. This shal't has also secured to it, between the arms k h two bevel-pinion spur-wheels, z', which take alternately into the bevel-wheel j, secured to the end of shaftj' of the driving-wheel.

On one end ot' the pinion-shaft g, l.ind attached thereto, vibrates the band-wheel k for operating the reciprocating compressore?. 0n the outerrim. b, ot'the driving-wheel are placed projecting pieces b2 b3. These pieces are for the purpose ot operating the long bent lever m, and placed against this rim so as to operate said lever at every half-revolution ot the driving-wheel. This lever m is pivoted to the plutform n at the point m and about midway between the stationary compressors c a. A pin, o. projecting from this lever, is i'or the purpose ot retaining a spriug,p, which forces the armi ture m2 outward and against the rim b. This lever has at either end notches cut in it for the purpose of receiving the projecting pinsp' p2. These pins are secured in the slide-plate 'q and on each side ofa slot, 1", cut in said plate,

for the purpose ot adjusting the compressor u2, part ot' which extends through the slot r, and is secured to the bottom ot the plate by a nut, s, as seen in Fig. 4.

Secured in front ot the platform n are two bent guards, t t, for the purpose ot' preventingr the cut grain from falling in the upper part ot the compressors while the operation ot' tying is performed.

Having thus described the diterent parts of' my invention and their connection with each other, I will proceed to describe their operation, as follows We will start the machine. The projection b3 on the outer rim ofthe driving-wheel being ready to operate the lever m, the small lever d hasjust thrown the pinion-\vheel i into gear with whel j, (this operation is not shown in the drawings) the band-wheel L' made one revolution and carried the compressor a? to the farthest end of the platform, as described in my Letters Patent of January 1, 1856, and,

it being there secured-by the notch in the lever m, the binder ties the bundle. ation of binding is going on and the machine moving forward, the arm ofthe small lever d being in one ofthe cams, which throws both pinions i Ii out of gear with the wheel j, and allows the band-wheel k, and consequently the While the oper- -f I iev .m-is operated b projection. W

direction of 'the band-wheel, and dair the compressor' a2 toward the opposite end oimhe l' platform. The grain having fallen during` the period of binding between the stationary compressor a' and the reciprocating compressor a, it rakes and compresses the grain into a bundle, ready for the other binder to tie. The notch catches onto the pin p2, and is held there until the wheel a has made another quarter# revolution, when the projection b2 operates the lever m and relieves the compressor, which, by this time, is ready to return, and vice versa.

By these means I produce the same results in a more perfect and practicable manner than by the arrangement of operation described in my former patent, as aforesaid.

pnion into gearfwitlr wheel j, rev the 2. The arrangementnd combination, with-.5 the cams for operating the compressor, of. the lever d, bevel-gearing j i i', and pulley-wheel e on the pinion-shaft, all arranged and operating for the purposes hereinabove set forth.

3. The guards t t, for the purposes substantially as herein set forth.-
